IMPROVED MACHINE lFOR'IVIAKING HORSESHOES.

To all whom, itmay concern:

Beit known that I, WILLIAM W. LEWIS, of Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Improved Horseshoe-Machine; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making part of this specification, in which- Figure l is a side view of my improved machine, one spindle, with its gear-wheel and attachments, being removed. Fig. 2 is a perspective view of the sliding yoke for giving motion to the movable former. Fig; 3 is a perspective view of the adjustable gage. Fig. 4 is a sectional plan of the shoe and movable and stationary formers at the commencement of the bending opera-tion. Fig. 5 is a plan of the shoe, movable and stationary formers, and revolving arms at the completion ofthe bending operation. Fig. 6 is a perspective viewof the entire machine.

Like letters represent like parts in all the figures.

My invention consists in a machineior bending horseshoes by means of revolving arms pressing the blank around a stationary former, and in various devices to effect the various stages of the bending operation in the best manner.

An essential advantage of my improved horseshoe-machine is that by bending the blank from the ends forward, the center being stationary, the power required is much less than by the old modes, where the blank was bent from the center, the ends remaining stationary, and the strain upon the metal from the same cause is proportionally less.

In the drawings, A A/ represent two adjustable gages, providedwith notches or recesses for receiving and holding the ends ofthe blank B. These gages are adjustable by the set-screws c c in the direction of the length of the blank for the purpose of receiving blanks of different lengths, and also for the purpose of presenting the blank to the center of the stationary former in equal lengths for the fore shoes,

or in unequal lengths for hind shoes. These gages slide upon and are'supported by the piece D, near the end of the vibrating arm E. This arm is pivoted at Gin such a manner that when not acted upon by the rollers F F Figs. 3 and 5, it will rest upon the point of the outer or curved end H, which acts as a stop; but when the rollers F F pass over the cams I I', Fig. 3, the outer end will be raised, carrying' with it the gages A A', with the blank B.

K is a movable former and blank-holder,

which is carried back and forth by the sliding I yoke L. The function of this former is to receive the blank from the gages, to present it to the stationary former and to the action of the revolving arms, to clamp it at the beginning of the bending operation, and to follow that operation until the shoe is formed. It may be easily removed from and attached to the projecting arm of the sliding yoke, so as to admit of the employment of any desired size.

The yoke L slides to 'and fro upon the platform or rest M, and motion is imparted to it by means of the rocking arm O and cam N. This cam is of such a form that the projection Nl will first throw the former forward to re` ceive the blank from the gages and clamp it to the stationary former, when the projection N causes it, by a second movement, to follow the blank to the completion of the bending operation.

The arm O is provided with a projection, P, which embraces a Wing, R, upon the cam N, by which the arm is drawn back after each forward movement. rlhe ends of the arm and projection P are protected. by rollers O', O, and P, to diminish friction.

The cam N is located upon the main driving-shaft S of the machine, midway between two beveled gears or wheels, one of which, T, is shown in Fig. l. These gears mesh into corresponding beveled wheels on the shafts U and U', causing them to revolve in opposite directions. These shafts carry the adjustable revolving armsV V', Figs. 1 and 5, upon the outer ends of which are t-he grooved rollersW V, Figs. l and 5. By the revolution of these arms toward the stationary former the rollers are caused to strike the ends of the blank, which are received in grooves, (see Fig. 4,) and, the arms continuing to revolve, to bend the blank around the stationary form X. These arms are made adjustable by means of the screws and nuts e e, Figs.'1 and 5, so as to accommodate them to blanks of. different size. The form X is removable, so that forms of dierent sizes and shapes may be readily employed.

The lower part of the shafts U U are provided with revolving disks Y Y', Figs. l, 3, and 5, Vcarrying the rollers F F', which act upon the cams I I', Figs. 1 and 3.

Z is a chute-board for discharging the shoes when formed, the shoes being removed or knocked from the stationary former by thev rods g q, Figs. 1, 4, and 5, which are driven down by the right-angled arma a and cam b upon the shaft S, and raised by the spring d upon the under side of the arm a. rIhese rods pass through slots ff, Fig. 4, in the platform, which permits them to be adjusted to differ-v ent forms, while the holes :v .r in the sides of each former give direction to the movement.

The operation of my machine is as follows: A blank is placed between the gages A A', the arm E resting upon the stcp H. By the revolution of the rollers F F over the cams I I the blank is raised until the upper side of the projections on the movable former K can pass beneath it. 'Ihe former K is then driven forward by the arm O, and the blank is received upon the projections and borne against the center of the stationary former X, the gages A A descending at thefsame moment. rIhe revolving arms V V then seize the ends of the blank and press them around the stastionary former, the movement being closely followed by the movable formel` until the bending operation is completed, as shown in Fig. 5. The arms then pass beyond the shoe, the movable former is drawn back, the knockers q q descend, and the shoe is thrown down upon the chute-board, as shown in Fig. l.

It is obvious that some changes may be made without materially affecting the principle of my machine. Thus the disks Y Y may bedispensed with, and the rollers F F may be mounted upon arms projecting from the shafts. A single roller and cam, only, may be employed to raise the arm. 'Iwo or more revolving arms may be employed upon each shaft, the other movements being accelerated to correspond, while the parts may be brought together by other and equivalent devices.

What I claim as my invention, and desire to.

secure by Letters Patent, is-

1. In combination with a xed former, two revolving bending-arms adjustable as to the extent of their projection from their axes of revolution, arranged to operate conjointly on the heated blank, in the manner substantially as described.

2. The combination of the adjustable revolving arms with the movable former and blank-holder and with the stationary former, substantially as described.

3. The reciprocating device K, constructed substantially as' described, and operating, in relation to the blank, in the threefold capacity of supporter, carrier, and former, in combination with the stationary former.

4. The combination, substantially as described, of the sliding yoke L, vibrating arm O, formers K and X, and the blank-holder.

5. rlhe lever E, with the gages or supporters A on one end and the cams I on the other, or the equivalent thereof, in combination with revolving rollers F, or their equivalent, for operation in conjunction with the cams, substantially in the manner and for the purpose described.

6. The combination of the cam N, arm O, and reciprocating device K, substantially as described.
